LOCKED RAZOR.

Application filed April 29, 1922. Serial No. 557,262.

To all whom it may concern Be it known that I, JULIAN W. FRETWELL, acitizen of the United States, residing at Danville, in the county ofPittsylvania and State of Virginia, have invented new and usefulImprovements in Locked Razors, of which the following is aspecification.

One object of my said invention is the provision of 'a locked razor-i.e., a razor so constructed that its blade is locked against removal andagainst surreptitious use by servants. Manifestly a razor characterizedas indicated may be placed in the 'hands of an insane man for legitimateuse without liability of the patient being able to remove the blade anduse the same in a suicidal effort. Also, a razor of the kind stated maybe left in his room by the owner without locking means being preferablycontrolled by a key to be carried by the owner, and manipulation of suchkey being absolutely necessary in order to dispose the blade for use.After use of the razor the key is introduced and manipulated -to put theblade and the.

razor as a whole out of commission, and the key is then carried away bythe owner. Another object of the invention is the provision in a razorcharacterized as set forth, of a flexible blade provided with amultiplicity of closely arranged apertures adjacent to each of its edgesso that in the event of an insane person seeking to pick at the bladewith a view to removing the same, the blade will be broken intofragments and rendered unfit for use.

. My improvements are designed more particularly for embodiment in-acertain well known type of safety razor, but I desire it distinctlyunderstood that it is within'the purview of my invention to embody theimprovement in a razor of any type, it being within the purview of myinvention to combine any kind of razor blade with means for locking theblade so as to preclude use of the razor by any one except the owner ora person having authority over the razor.

To the attainment of the foregoing, the invention consists in theimprovement as hereinafter described anddefinitely claimed. In theaccompanying drawings, formingpart of this specification 1 Figures 1 and2 are sections at right angles to each other taken longitudinallythrough a well known type of safety razor constructed in accordance withmy inven-. tion. t

Figure 3 comprises disassembled elevations of parts embraced in the saidrazor together with an elevation of the key for controlling the razor.

Figure 4 is a plan view of a blade of flexible character, weakened inaccordance with my invention for the purpose indicated.

Similar numerals of. reference designate corresponding parts in all ofthe views of the drawings. 1

The blade 1 illustrated s of the transversely flexible kind with duplexsharpened edges 2. The blade is also shown as prov vided with a centralaperture 3 and other apertures 4. They multiplicity of minute apertures5 in the blade 1 as shown in Fig ure 4 may be employed or may bealtogetheromitted without affecting the major portion of my invention. Iprefer, however, to employ the said minute portions 5 inasmuch as theyimpart to the blade the capacity, of

readily breaking into fragments in the event of an insane person workingat the edges of the blade in an attempt to remove the same from theremainder of the razor.

In addition to a transversely flexible blade, the razor shown comprisesa tubular handle 6, a guard 7 with fingers 8 fixed to one end to thehandle 6, a blade clamp ng cap 8 to which is fixed a shank 9 threaded at10, and a locking member 11 slidable and rotatable-about its axis in thehandle 6. Appropriately-secured in the heel end of the handle -6 is amember 12, a portion 13 with a key seat 16. The said key seat is forcooperation with the reduced end 17 of the key 18, Figure 3, which key18 is provided with an appropriate handle 19. Theblade clamping capshown'is provided in addition to the stem 9 with studs 20, said 'studs20 being designed to occupy apertures 21 in the guard 7 for the ordinarywell known purpose.

It will be apparent from the drawings that when the'blade 1 ispositioned as shown in Figures 1 and 2, the razor cannot be used nor canthe blade 1 be removed. Toput the razor into condition for-use it isnecessary to introduce the key 18 through the tubular member 12 and intoengagement with the locking member 11 about its axis through the mediumof the key until the transversely flexible blade 1 is reduced to asubsequently flat state and so that its edges protrude sufficiently farbeyond the longitudinal edges of the clamping cap 8 forshaving purpose.After use of the razor the owner or a keeper having effort over therazor introduces the key 18 and by turning the member 11 re turns theparts to the positions shown in Figures 1 and 2, and then takes the keyaway with him.

When it is desired to clean the razor the member 11 is manipulatedthrough the me dium of the key 18 to a sufficient extent to permit ofthe removal of the cap 8 and the blade 1, and then after the cleaningoperation the said blade and cap are replaced, and the member 11 isadjusted through the medium of the key to position the parts as shown inFigures 1 and 2.

Notwithstanding the capacity of function ascribed to my improvement, itwill be readily appreciated from the foregoing that a I razor of thetype indicated embodying the invention is simple and inexpensive inconstruction and is calculated to last quite as long as an ordinaryra'zor of corresponding t I have entered into a detailed description ofthe construction and relative arrangement of the parts embraced inthepresent and preferred embodimen of my invention in order to impart a inclear and exact understanding of the said embodiment. I

do not desire, however, to be understood as confining myself to the saidspecific construction and relative arrangement of parts inasmuch as inthe future practice of the invention various changes and modificationsmay be made such as fall within the scope of my invention as defined inmy appended claims. 7

Having described my invention, what I claim and desireto secure byLetters-Patent, is V 1. A locked safety razor comprising a hollow handlecarrying a guard, a clamping cap havin a stem, a transversely flexibleblade on t e stem and interposed between the guard and cap, and alocking member completely disposed and operable in the hollow handle andengaged with the stem of the clamping cap to secure the blade in an idleposition and against removal and provided entirely within the hollowhandle with a key portion tobe engaged with a key separable from therazor.

2. A locked safety razor comprising a hollow handle carrying a guard, aclamping cap having a stem, atransversely flexible blade on the stem andinterposed between the guard and cap, and a locking member disposed andoperable in the hollow handle and engaged with the stem of the clampingcap'to secure the blade in an idle position and against removal, thesaid locking member being key controlled, and the key being removablefrom the hollow handle and separable from the razor.

n3. In a razor, the combination of a tubular handle with a guard at oneend, said guard having a central aperture and other aper tures, aclamping cap opposed to the guard and having a stem extending throughthe central aperture thereof and into the tubular handle and providedwith a threaded por-, tion, a tubular member secured in the heel end ofthe handle, a locking member movable about its axis in the tubularhandle and having a kerf or socket in its heel end and also having athreaded socket receiving a portion of the cap stem, and a transverselyflexible blade apertured to receive the stem.

and studs on the cap and interposed between the said cap andthe guard,said looking member being adapted to be operated by a key, and-the saidkey being separable from the razor.

V at. As a new article of manufacture, a transversely flexible razorblade having a sharpened edge and also having adjacent to said edge amultiplicity of minute, closely arranged apertures. g

In testimony whereof I aflix my signature.

JULIAN w. FRETWELL.
